Intelligent homes consist of ubiquitous sensors, home networks, and a context-aware computing system. These homes are expected to offer many services such as intelligent air-conditioning, lighting control, health monitoring, and home security. In order to realize these services, many researchers have worked on various research topics including smart sensors with low power consumption, home network protocols, resident and location detection, context-awareness, and scenario and service control. This paper presents the real-time metabolic rate estimation method that is based on measured heart rate for human adaptive appliance (air-conditioner, lighting etc.). This estimation results can provide valuable information to control smart appliances so that they can adjust themselves according to the status of residents. The heart rate based method has been experimentally compared with the location-based method on a test bed.

In this paper, we propose a method for the efficient power use in power outage. The cost is high and conversion into the other function is difficult since the terminal used in conventional home network system has a dedicated function. This method is based on home network system employed with photovoltaic system. Throughout the modularization of the terminal, the variable function and cost reduction can be achieved. Additionally the unit cost can be reduced by using the power line communication. The prototype of light-control terminal has been implemented. The experimental results with the terminal show the performance of light-control system and the possibility of the commercialization can be achieved.

A security robot system named EGIS-SR is a mobile security robot through one of the new growth engine project in robotic industries. It allows home surveillance through an autonomous mobile platform using onboard cameras and wireless security sensors. EGIS-SR has many sensors to allow autonomous navigation, hierarchical control architecture to handle lots of situations in monitoring home surveillance and mighty networks to achieve unmanned security services. EGIS-SR is tightly coupled with a networked security environment, where the information of the robot is remotely connected with the remote cockpit and patrol man. It achieved an intelligent unmanned security service. The robot is a two-wheeled mobile robot and has casters and suspension to overcome a doorsill. The dynamic motion is verified through $ADAMS^{TM}$ simulation. For the main controller, PXA270 based hardware platform based on linux kernel 2.6 is developed. In the linux platform, data handling for various sensors and the localization algorithm are performed. Also, a local path planning algorithm for object avoidance with ultrasonic sensors and localization using $StarGazer^{TM}$ is developed. Finally, for the automatic charging, a docking algorithm with infrared ray system is implemented.

In this paper, an intelligent home network middleware interconnection adapter between devices was designed. Home network middleware interconnection adaptor is present in UPnP, LonWorks, LnCP, HAVi, etc. Various types of middleware and for use of a number of middleware is required to modify an existing system. But this study designed by middleware interconnection adaptor a number of existing middleware systems without modification was designed to allow interlocking. The Performance evaluation of designed interconnection middleware adaptor produced by various companies was used devices, experimental device was implemented. And mobile application was developed by using developed interconnection middleware adaptor. Also the performance was evaluated in a mobile application.

In this paper, we design a ubiquitous home automation system for Korean domestic 33-Pyung Apartment based on USN environment. The core of this home automation system is to give Home the 'Intelligence' so that the house can analyze and memorize the occurrences and react spontaneously on the user requirements by means of the World Model, USN, and LBS etc. Ultimately, the resident of this intelligent home might access all of these ubiquitous environments without any feelings about the equipments and peripherals. The methods of user identification, image recognition, and the ultrasonic sensors locations have been applied to Korean domestic 35-Pyung Apartment, but they will be easily generalized to be an extended model because of the flexibility of the World Model. which are confirmed by the imaginary scenario presented at the end of the main left.

The recent trend in home network system includes intelligent home environments that remote monitoring and control service is achieved without restrictions by device types, time, and place. Also the use of a vacuum robot in homes is gradually generalized on account of the convenience of the use. In this paper, we proposed and realized new home-monitoring system with the employment of an self-movement robot as one trial for realizing an intelligent home under home network environment. The proposed system can freely monitor every where in home, because the system effectively overcame the surveillance limitations of the existing monitoring system by attaching a Wireless Router and WebCam to a commercial vacuum robot. The outdoor users of this system can readily monitor any place which they want to supervise by controlling a vacuum robot with mobile telecommunication devices such as PDA. The wireless router installed with Linux operation system "OpenWrt" made it possible for the system users to transmit images and to control a vacuum robot with RS-232 communication.

Home Networking will be implementing the interactive network by home appliances over wireless/wireline network framwork. That is, Home appliances, which are being operated within home space configure the network through wireline/wireless network infrastructure for interworking and interacitive services by external internet access. Based on home networking, smarthome is home space where can use automatic telecommunication and interactive service by home appliances. we can call smarthome based on home networking infrastructure as the conceptual gateway for evolving future converged space like u-city. From simple home control service to home automation service over home networking infrastructure, smarthome service is evolving to up-to-date intelligent life environment in growth of IT technology. however, its service model development was based on supplier-centered based on advanced IT technology. because of this situation, smarthome service has not been acknowledged IT underprivileged people as well as IT early-adaptor. so, this research paper will consider and try to find out what will be the feasible factors to make the best service for IT underprivileged people.

The digitalization of our society has brought on the digitalization of housing design and human life. Thus, the concerns for developing digital home have increased. However, most of them has focused on digital technology, not human. This study was intended to examine the residents' housing needs for digital home and to suggest the design guidelines of digital home. The subjects were 400 housewives who lived and used internet in $85m^2$-sized housing unit in the new apartment complex, Busan. The important aspects in digital home design, the residents' needs for digital home design, and the needs for digital system in digital home were examined. The subjects were relatively young in their ages. Also, they had relatively high educational level and middle income. On the base of their housing needs for digital home, the design of digital home like as followings would be desirable: 1) the safe and secure design and digital system, 2) the design to improve residents' health and encourge family interaction, 3) human, warm, and soft interior mood, 4) space composition different from the existing one.

We present the motivation, design and implementation of a smart home system in Korea. Our system is open, extensible, integrated, intelligent, and usage-centric. We detail the challenges and key design requirements for the smart home system based on our past experiences, and show how convergence system design is a capable methodology for enabling an integrated and multi-faceted home management system that encompasses energy management, home appliance control, environment management, u-health, and living support functionalities under a single unified design. Using energy management as a specific case study, we demonstrate how convergence system design can encapsulate technology heterogeneity and hardware-software disparity without compromising simple yet powerful user interfaces.
